A man of weight W is standing on a lift ...

A man of weight W is standing on a lift which is moving upwards with acceleration 'a'. The apparent weight of the man is :

A

W

B

Zero

C

`W(1-(a)/(g))`

D

`W(1+(a)/(g))`

Text Solution

Verified by Experts

The correct Answer is:
d
`R-mg=ma`
`R=mg(g+a)`
`R=mg((1+a)/(g))`
`R=W((1+a)/(g))`
Hence correct choice is (d)
